mysql_real_escape_string() not safe when SET NAMES is used
use mysql_set_charset() instead.
Note: This is the preferred way to change the charset. Using mysql_query() to execute SET NAMES .. is not recommended.
SET NAMES is usually used to switch the encoding from what is default to what the application needs. This is done in a way that mysql_real_escape_string doesn’t know about this. This means if you switch to some multi byte encoding that allows backslash as 2nd 3rd 4th… byte you run into trouble, because mysql_real_escape_string doesn’t escape correctly. UTF-8 is safe…
Safe way to change encoding is mysql_set_charset, but that is only available in new PHP versions
